RANG-E.

To all whom it may concern:

Be it known that I, HENRY S. MARVIN, a citizen of t-he United States,residing at San Diego, in the county of San Diego and State ofCalifornia, have invented a new and useful Range, of which the followingis a specification.

This invention relates to ranges of the form known as French ranges andparticularly to those ranges wherein a series of ovens are heated from asingle fire-box or fire-pot at the end of the series.

One object of the present invention is to provide means whereby the heatis more uniformly distributed from the fire-pot to series of ovens andto the top plate of the range.

Another object of the invention is to provide means for maintaining thejoint between the front wall of the range and the top plate.

The invent-ion further comprises means for separating the ovens of therange.

Other objects of the invention will appear hereinafter. Y

The accompanying drawings illustrate the invention.

Figure l is a longitudinal vertical section of a range. Fig. 2 is ahorizontal section thereof. Fig. 3 is a transverse section on the line@a3-x3 in Fig. 1. Fig. 4 is a partial plan. Fig. 5 is perspective of alintel plate serving asa spacer for the ovens. Fig. 6 is a perspectiveof a joint plate for the front of the range. Fig. 7 is a verticalsection across the joint between the forward portions of the ovens.

The range is of elongated rectangular. shape built up with a brick workfloor 1, brick work back 2, brick work end walls 3, 4, and metal top andfront plates. Metal plates 5 are provided at each end of the rangeoutside of the end walls and the end plates 6 of the front of the rangeconnect with said metallic end plates at the ends of the range.

The front of the oven is built of a plurality of sections each formed asa metal plate 8 provided with a flange 9 to rest on the base and with acentral opening surrounded by an inturned flange 11, said opening beingclosed by a door 12. Flange 9 is fastened to base strips 13, anchoredinto back wall 2. Each section 8 is fastened to the adjoining section orto the end plate 6 as the case may Specication of Letters Patent.

be, by the joint plate 14, see Fig. 6, which has laterally extendingprojections 16 perforated to receive fastening bolts or rivets 17. Oneof these joint plates is placed back of each joint between the adjacentsections of the oven front and is secured to said sections by the rivets17 so as to bind the sections together in a continuous front. The ovens18'are formed as sheet metal boxes fastened to and extending rearwardlyfrom the lianges 11 around the oven doors, said ovens being closed atthe rear by plates 20, and said ovens resting on a rail or longitudinalmember 21 which may be formed as a metallic T-bar extending from the endwall of the range farthest from the lire-pot under the ovens, nearly tothe fire-pot, but leaving a space or passage 22 adjacent to the fire potfor the passage of the products of combustion from thefront to the rearof said rail. The end of rail 2l nearest the lire-pot is bent forwardlyto deflect the hot gases under the front part of the first oven.

The fire-pot 25 is located at one end of the series of ovens and has alining or wall 26, grate 27, ash pit 28 below the grate, heating coil29, if desired, above the grate. The combustion chamber of the fire-potextends above the grate to the top plate 23 and rear wardly over theadjacent oven, and the wall of the re-pot on the side toward the ovenflares or is inclined upwardly and rearwardly as at 26 and the adjacentcorner of the lirst oven is similarly formed, as at 18, forming arearwardly converging space communicating with the combustion chamber ofthe fire-pot and with a flue 30 extendingv above the series 'of ovens,so that the flame and the products of combustion are drawn evenly andgradually into said flue from the combustion chamber, avoiding theconcentration of the heat directly over the combustion chamber such asgenerally occurs with an abrupt transition from the combustion chamberto the flue.

At the far end of the flue the downtake 31 is provided in the end wallof the range, communicating at its upper end with the flue 30 and at itslower end with the return or bott-om flue 33 which extends forwardlyunder the series of ovens and at its end communicates through thepassage 22 aforesaid with a back ue 32 leading back of the series ofovens throughout the height thereof and communicating at its end into astack opening or flue 32. The adjacent ovens are separated suiiicientlyto allow hot gases from the bottom flue to enter between them to heatthe ovens, and this intervening space is closed at the top by a lintelplate 34 formed of flat metal (see Fig. 5) and having a leg 35 at oneend and extending downwardly to rest on the longitudinal rail 21aforesaid. Said lintel extends transversely between the adjacent ovenwalls to space the same, and close the opening therebetween. Said lintelhas at each side at the front end thereof an upwardly extending arm 36bent over to rest on the top of the ovens to support the lintel plate.Fire brick, indicated at 38, may be placed on top of the lintel platesto further close the space between the ovens 3. To insure closure at theback of this space, overlapping plates 39, 40 are provided, said platesbeing secured to adjacent ovens and making a slip joint with oneanother, so as to maintain closure between the return flue 33 and theback flue 32.

The top plate 23 is divided in sections and is secured by screws 23 tostraps 2. The back wall 2 has a forwardly extending flange 4l supportedby a plate 42 anchored in the back wall and resting on a T-rail 43 whichextends longitudinally above the ovens and rests thereon. The said topplate rests along its front on top of the front plate which has alongitudinal roove 44 to receive a body or strip 45 of packing materialfor closing the joint. Over the combustion chamber, the top late isprovided with removable nested lids 46, 47, 48, the outer lid 46 beingsplit to correspond with the joint between two sections of the stove topand having a rabbeted joint 49 between its two parts.

What I claim is l. In a range comprising a series of ovens, supportingmeans extending longitudinally beneath said series of ovens, and spacingmeans for the ovens consisting of a plate having a Yleg to rest on saidsupporting ovens and sliding on one another to form av slip joint.

3. A range comprising a series of ovens, said ovens being separated fromone another forming intermediate spaces, back and end walls for therange, a top plate forming in conjunction with the back and end walls aflue extending longitudinally over the series of ovens, and thewalls ofthe range forming ues extending downwardly at the rear of the series ofovens, then under the series of ovens and longitudinally back of theseries of ovens, means for closing the spaces between the ovens at thetop and back thereof, a front plate for the range comprising a pluralityof sections, each section having an oven attached thereto, means forjoining adjacent sections and closing the front of the spaces betweenthe ovens consisting of a plate extending back of the two sections attheir joint, and means fastening said plate to the edge portions ofadjacent sections.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 12th day of December 1908. u
